Spatial dataset: Enable installing based on a bounding box

[henrykironde]

The goal is to enable users to install just the area of the spatial data that they require

The good thing is gdal can do this.

The proposed structure could be as below or otherwise.
retriever install postgres bioclim --bbox -14648825.0817 3552130.7825 -14627575.5878 3565507.2624

Idea:
After the data retriever has downloaded the raw data. we clip the images and used in the clipped images
